Key Takeaways
- ROI (ROMI) is a basic profitability indicator that helps you understand whether your marketing investments are paying off, rather than a universal «measure of success».
- In online marketing practice, ROI and ROMI almost always mean the same thing, since it is the promotion costs that are analyzed, rather than all business investments.
- ROI = 1 is the break-even point, where marketing costs are half of the revenue generated; anything below is a risk zone, anything above is a growth zone.
- ROI does not take into account the delayed effect of marketing, the impact on brand awareness, and behavioral factors that cannot be directly converted into money.
- A high ROI does not always mean strong marketing, just as a low ROI does not always indicate failure — context and assessment horizons are important.
- ROI should be used as a guide for decisions, not as the sole criterion for evaluating the effectiveness of a marketer or channel.
ROI is a coefficient that shows the level of profitability or unprofitability of the entire business or a separate business process. The tool allows you to perform variable calculations using numerous formulas that can be difficult for an untrained person to understand. When talking about Internet marketing, they mean the simplest formula that shows the ratio of the amount of profit to the amount of investment, or the coefficient of return on investment. In the context of digital promotion, this indicator is especially important, as it allows you to assess the effectiveness of each customer acquisition channel. That is why businesses should consider long-term tools, such as SEO promotion, which, with the right strategy, ensure stable traffic and profit growth.
What is the difference between ROI and ROMI?
The difference between ROI and ROMI is not fundamental and concerns only the application. The word “marketing” was added to the second name, resulting in “return on marketing investment” — return on marketing investments, or, to speak more strictly about what Romi is, it is the profitability ratio of marketing investment costs.
ROI is used to calculate the profitability of a business and includes accounting, including, investment costs that are not related to promotion, for example, investments in fixed assets (construction of a building, rental of equipment, scientific and technical developments, etc.).
So romi is the same tool, but more narrowly focused. It is used when you need to calculate the impact on revenue of not all investments, but only those that are related to promotion of a brand or product. Thus, in Internet marketing, when talking about ROI, they almost always mean ROMI. In this article, we will use these terms interchangeably.

How to measure and calculate?
For the purposes of assessing the effectiveness of a marketing campaign or its set, a simple formula is used:
RO (M) I = (revenue received - marketing expenses) / marketing expenses
Let's consider a simple example of how to calculate roi,with the following initial data:
- revenue received = $ 800
- marketing expenses = $ 460 RO (M) I = (800 - 460) / 460 = 0.739
Sometimes it is suggested to multiply the resulting number by 100%, but this has no fundamental meaning and is mathematically incorrect since numbers are not multiplied by percentages. What does ROI = 0.739 mean? It says that the promotion costs amounted to more than half of the income received.
And what is half in the form of a coefficient?
As in many other cases in which any coefficient is calculated, the equilibrium state is taken as 1.
For clarity, let's give a simpler example:
- income received = $ 800
- marketing costs = $ 400
RO (M) I = (800 - 400) / 400 = 1
From this example, we see that the obtained ROI = 1 corresponds to the initial data, in which the costs (expenses) amounted to half of the income received.
Accordingly, ROI = 0 for the original data, when profit equals cost, i.e. no net profit was received at all:
RO (M) I = (800 - 800) / 800 = 0
Thus, ROI shows whether marketing investments were successful. How successful they were is a matter of assessment in each specific case. Obviously, the higher the ROI value obtained, the better.
Why calculate ROI in Internet marketing?
Calculating ROI for a marketing campaign has no advantages over the traditional expression of costs and expenses in money or percentages. So, for the first example from the previous paragraph (income = $ 800, expenses = $ 460), a more understandable calculation can be made:
460/800 x 100 = 57.5
From the calculation, it is clear that the costs of the campaign amounted to 57.5% of the income received (which corresponds to ROI = 0.739). In most cases, this is enough to understand the effectiveness of the work performed.

Both methods of estimating the theoretical and conditional, which are explained as follows:
- They describe some ideal situation with a precisely known profit that was obtained as a result of a certain marketing action. In reality, it can be difficult to understand what part of the profit was generated from the targeted marketing impact.
- Marketing "return" cannot always be recorded in the form of profit now. Often, promotion campaigns have a delayed effect, for example, the user did not take the target action within the framework of the campaign but did it a year later, with a different product (for example, with a new smartphone model). Equally important, such "abstract" marketing goals as "increasing brand awareness" cannot be calculated mathematically correctly.
Let's summarize
Is RO (M) I useful?
Yes, in many cases (for example, when launching an online store and involving many advertising channels at the same time) it can give a simple and clear idea of the effectiveness of an advertising campaign.
Does RO (M) describe the effectiveness of a marketer's work exhaustively?
Unfortunately, no. The method is quite limited. Modern marketing is largely based on intuition and irrationality, including that associated with the peculiarities of human behavior. These areas are difficult to account for.
FAQ
1. Is it correct to multiply ROI by 100%? From a mathematical point of view, no. ROI is a ratio, not a percentage. Multiplying by 100 is a simplification for presentations, but it can be misleading.
2. Can you evaluate a marketer's work based solely on ROI? No. ROI does not take into account brand effect, deferred sales, complex customer interaction scenarios, and external factors. It is only one indicator, not the final verdict.
3. Why does ROI not always show the real effectiveness of advertising? Because some marketing results show up over time. A user might not buy right away, but come back later or choose another product from the same brand.
4. Should you calculate ROI for each campaign separately? Yes, but with caution. Individual campaigns can work toward a common result, and evaluating them separately doesn't always show the real picture.
5. Why is ROI needed in internet marketing at all? ROI helps you quickly understand the order of numbers, compare channels with each other, and make management decisions. It is a navigation tool, not a precise measuring device.
